Buick LaCrosse eAssist Debuts at LA Auto Show
Buick brings efficiency to luxury car market with LaCrosse eAssist hybrid sedan
Buick has brought efficiency to the luxury car market with the creation of its LaCrosse eAssist, a full-size hybrid sedan making its debut at this year's Los Angeles Auto Show. Fuel-saving technology in the 2012 LaCrosse eAssist is expected to increase the vehicle's fuel economy by 25% over the 2011 Buick LaCrosse, giving it a highway fuel-economy of 37 mpg, the highest in its class.
The Buick LaCrosse eAssist is powered by a 2.4 liter four cylinder Ecotec gasoline engine with direct injection that is connected to a 115 volt lithium-ion battery pack and a 15 kilowatt motor-generator. The hybrid car saves on fuel in a variety of ways, including regenerative braking, drawing up to 11 kilowatts of electric power from the battery when accelerating, automatically turning off the engine when the car stops, cutting off fuel when the car decelerates, and intelligently charging and discharging the battery pack.
In addition to being the most energy-efficient car in its class, the Buick LaCrosse eAssist will also be one of the least expensive, with an expected retail price of $30,000. Daryl Wilson, Buick's lead development engineer for the LaCrosse, seems especially pleased with the hybrid car, asserting that the LaCrosse eAssist "points to the future of vehicles" with its efficiency and performance. Buick has so much faith in its new hybrid that it is making the eAssist system standard in all of its new LaCrosse models that come with a 2.4 liter Ecotec engine.
